SPECIFICATION forming partl of Letters Patent No. 692,6-68, dated February 4, 1902.

Application iiled J'uly 19, 1900.

To all whom, it may concern.-

Be it known that I, DAVID HURST, a citizen ofthe United States of America, and a resident of Mansfield, county of Richland, State of Ohio, have invented certain new and usefullmprovements in Motors, of which the following is a specication.

My invention relates to improvements in motors, and is more particularly applicable to those operated by the power of steam and atmospheric pressure.

The objects of my invention are, first, to furnish a motorthat is reliable, efficient, and practical in its operation,as well as economical in the saving power; secondly, to afford improved facilities for the proper adjustment of parts of the device which regulate the ad! mission of steam and prevent the admission of air, as well as to provide means whereby to elit'ectually close the overflow pipe at any point of the upward stroke of the piston, and, thirdly, to provide a means for adjusting the rotation ofthe shaft connected thereto.

' When it is desired to operate the motor, steam is admitted into a chamber iilled to a given point with water by means of suitable pipe connections. The water is brought in contact with the bottom of a piston, and thel pressure of the steam against this body of water forces the piston upward and completes the upward stroke of the piston, operating the mechanism provided for ref., ulating` the motor, together with the connecting mechanism, more particularly described hereinafter and fully pointed out in the claims. The admission of the steam into the chamber forces the air and excess of water from conin an auxiliary chamber. This check-valve automatically closes on or before the completion of the upward stroke of the piston. When the steam is cut off from the water-chamber, condensation takes place therein, because the water in said chamber has been heated by the steam and is subsequently cooled by a waterjacket which surrounds the waterchamber, and thereby produces a vacuum. The Valve-gear may be adjusted to cut oit the steam at any point during the upward stroke of the piston by means of a trip. The piston Vin cross-section.

is then forced downward by means ot' atmos- Serial No. 24,197. (No model.)

pheric pressure, the weight ofthe piston and its connections being counterbalanced.

In the drawings I have shown my motor' attached to the driving or feeding shaft of a mechanical Stoker, to the operation of which it has been found to be particularly adapted. I do not, however, confine myself to this, as it is obvious'to one skilled in the art that it can be adapted to operate other machinery as well which does not require.

a high pressure of steam without deviating from the principle of iny device.

Having fully described the objects and the mode of operation of my invention, I will point out how yI Vattain these objectsv by the mechanism illustrated in the accompanying drawings, inrwhich- Figure l is a side elevation of the motor, showing the valve-gear, check-valve mechanism, stoker connections, and pipe connections used to regulate the motor. The waterchamber b, chamber C, the cylinder f, the water-jacket E, and bed-platev a are shown Fig. 2 is a plan View of the bed-plate, chamber C, piston H, and trunnion support or standard d, other parts being removed. Fig. 3 is atop view of a device used to connect the motor to the driving-shaft of anyfdevice which it is desired to operate. Fig. 4 is a side view of a iiat bar E2, to which are attached the bell-crank lever c3, spiral springs f2 g3, and pins for operating the trips.

Fig. 5 is a side View of thebracket or frame to which are attached thegparts of the valvegear mechanism, and Fig. 6 is a plan View in perspective of 4my peculiar check-valve and pipe which isattached to the head of the chamber C.

Similar characters referto similar .parts throughout the several views.

The reference-letter a designates the bedplate, to which are attached the water-chamber b, post c, trunnion-support d, valve-gear bracket e, and cylinder f, the whole constituting the framework of`my motor. Steam is admitted into the chamberv b through the angle globe-valve e4. The water inthe chamberb is forced downward therein and out through the pipe connect-ions g g, producing a pressure against the bottom of piston I-I and causing the piston to make its upward the interior of the piston.

stroke. The piston has four lugs t t' made integral therewith and projectinginwardly from These lugs are disposed diametrically opposite each other. A hole is drilled and tapped in the lugs, and collar bolts j j, having square heads cut thereon, are screwed therein. The lower portion of the piston is turned to fit the cylinder, while its upper portion 7c is turned smaller in diameter than the inside diameter of the cylinder, thus leaving an area between the upper portion ot' the piston and the inside diameter of the cylinder for the purpose of inserting packing a; therein. A piston-ring L, having a flange m extending downward and fitted to the inside of the cylinder, is attached to the piston by means ot' the collar-bolts j j, said bolts being inserted in slots 'cut in a circumferential fiange m2, made integral with the piston-ring L, said slots coinciding and correspending with the lugs 'L7 i'. on the piston H. The piston-ring has a tapered rib or ring n made integral and extending upward, the purpose of which is to provide means whereby lubricant may be contained between the rib n and the side of the cylinderf. In the center of the piston a hole is drilled and a bolto is inserted. A stud e', provided with upstanding lugs, is screwed on the bolt o, the lugs having apertures formed therein. A piston-rod p is then placed between the lugs of the stud and is attached thereto by means of a bolt y, passing through each side of the slot and the boss or end ot' the piston-rod. The airvent Q is inserted in the top of the piston. This air-vent is for the purpose of permitting the escape of any air or gas in the eylinderf when the piston is making its downward or inward stroke in order that such air or gas may not operate as a cushion to retard and prevent the descent ofthe piston into the cylinderf. The air-vent Q consists of a tube secured to and extending through piston l-I and formed with a bend or downward curve at its highest point, the free end terminating in a valve ot any approved construction, which permits the air to escape from beneath the piston. The upper end ot the piston-rod 2J is connected to one end of the walking-beam o', this beam having a slot cut in each end thereof for the purpose ot' receiving the upper ends of the piston-rod j; and connecting-rod s. The beam 'l' has a trunnion Z made integral therewith and projecting transversely from the center of the beam. This trunnion is fitted to and supported in bearings 3 in the trunnion-support d. The connecting-rod s is secured to the beam by means of a bolt passing through the aperture in the end thereotl and through the end of the beam similarly to the piston-rod. The connecting-rod passes through and swings or rcciprocates in a slot u cnt in the bed-plaie.

A split sleeve u, having projections or w, is bolted on the rod s where it passes through slot it, the projections on the sleeve being so arranged with reference to the slot that they will act as stops for the upward and downward stroke of the piston and beam by coining in contact with the sides of the slot. This' split sleeve can be adjusted to correspond with the adjustment of the valve-gear mechanism presently to be described. The opposite end of the connecting-rod s is secured to a swinging lever w, which lever is provided with a slot 5. The connecting-rod is secured to the lever w by means of a bolt passing through the slot in the lever and an aperture in the end of the connecting-rod. The swinginglcver w is slotted longitudinally at 5 and 10 to permit of the adjustment of the connectingrod and increase the feed or rotation of thedrive-shaft Y, supported in bearings in the swinging lever. An ear z' is formed at the free end of the lever, having a hole cut therein to permit a weight 4- ot any suitable kind or size to be hung thereon to counterbalance the weight of' the mechanism secu-red on theend of the piston-rod p. One or more pawls a are inserted in a slot 6 formed in and longitudinally of the swinging lever wat a point in said lever that will bring the ends of the pawls in contact with the teeth of ratchetwheel d2, and a bolt 7 is passed through the opposite ends of the pawls to retain them in place on the swinging lever and form a pivot therefor.

The ends of the pawls that operate the ratchet-wheel a2, which is keyed solidly on the driving-shaft Y, are made of different means of regulating the rotation of the driveshaft.` By placing one pawl in contact with the ratchet-wheel the drive-shaft is rotated more or less, according to the pitch of the teeth. By placing two pawls in Contact the rotation of the shaft is increased, each pawl increasing the rotation ot the drive-shaft as it is thrown in contact with the ratchet-wheel.

The swinging lever yw is attached to post c by means ol' a split sleeve 1).` A slot 12, cut in said sleeve at right angles with the hole Ui in said sleeve, affords a means :li'or securing and retaining the swinging lever w in position on the post c. The sleeve b can be adjusted on the post c to coincide with the adjustment of the mechanism of the valve-gear and piston. A bracket b3, having two arms curved slightly in opposite directions and made integral therewith, is attached to the top and in the center of the walking-beam, these arms having adjusting-screws c placed in the end thereof. Between the arms of said bracket a flange or upwardlyprojecting lug c2 is formed, having a slot formed therein longitudinally ot' the beam. A lever d is secured to this fiange by a bolt and is pivotally held in an upright position therein. The throw ol this lever d is regulated by the adjustingscrews c. A connecting-rod e8 is attached to the end of the lever d and connects with the bell-crank lever c. This bell-crank lever is pivotally attached to the bracket e, at the end ot' the loop in the bracket, by means of a Ion` lengths, the purpose of which is to af't'ord a IIO bolt which passes through the angle of the bell-crank lever. The opposite end of the' bell-crank lever vc3 is attached to the iat bar E2, which is inserted in a slot c7 formed in the top of the loop on the bracket e, the slot made to lit said bar, which latter passes through a similar. opening in a' guide e2, secured on bracket c. To the lat bar E2 a lug'8 is riveted. This lug extends away from the bar e2 and has attached at itsl outer or free end thei straight portion f of a spiral spring f2, the straight portion being inserted under a setscrew f7- inthe lug 8. This screw is used to adjust the tension of the spiral spring. Pins f3 are inserted in slots cut-in the at bar E2, Whichpins extend from the sides of the bar, to operate the trips g', by means of which the admission of steam into the Water-chamber b Vis regulated. The pins come in contact withv the trips g as the fiat bar E2 is reciprocated and operate the trips to close or open the angle globe-valve E4 alternately by means of the spring-catch regulators h3.

One end of the spiral spring f2 is turned to form a hook and is inserted in a 'hole in the spring-catch lever H. The opposite end of the lever H is fulcrumed ingthe projecting. arm H2 of the bracket e.' A second spiral rspring g3, having both ends turned to form hooks, is connected to the'end of the lever H' and the end of the lever j', respectively, thereby providing a tension to sustain the levers H and 'j' in position to automatically close and open the angle globe-valve E4. Two square' pins h2 are placed in the levers H and j', and as the Valve-gear ymechanism is operated'by the motor these pins interlock with catch-springs h3. 'These catchesprings are attached to the bracket e with the catch portion of each pointing in opposite directions and in direct alinement with each other.

Tothe lever H', at a point 9 close to the fnlcrum, a rod J2 is attached. The lower end of this rod is secured to the stem J3 of the angle globe-valve E4.V The rod is apertured on both ends, and is secured to the lever H and the valve-stem ll3,respectively, by means of bolts "passing through the end of the rod andlever and the opposite end of the rod and valve-stem, respectively. An open cylinder f,-having flanges cast on the top and bottom thereof, is bolted to the bed-plate a over the orifice of the pipe g. To the piston-rod p lan' arm or dog k is attached. The dog when the piston is making its upward stroke comes in contact with theprojecting lug k2,attached to a swinging bar 7c3, pivoted to an arm L on the'brackete. Both ends'of the bar 7c3 are turned at right angles withthe body portion of the bar. On one end of the bar a hole is 1T- drilled, into which a rod L2 is inserted, the

upper endet which rod 'is threaded and a weight L3 secured thereon. The lower end of' the rod passes through the bed-plate a and is adj usted by the collar L4. A second weight L5, having a slot cut in the bottom thereof, is placed on the bar or lever 7c3 and slides thereon.

A rod m is received in and projects through the opposite end of the bar K3, which rod isl provided with adjustingLnuts'm2, fitting on either side oftheend of the bar 7c3. vThebar` m passes down through the sleeve 'n' andl comes in contact withthe top of the checkvalve n2. This rod m is adapted to close and open the check-valve in the chamberOwhen the motor is in operation.

chamber C and keeps the water in, said chamber at its proper level. The check-valve n2 is constructed to titthe circumference of the relief-pipe o2 and is placed on the top thereof.

A hole o3 is drilled through said check-valve the piston is making its upward stroke, the frodp brings the dog lo' in contact with lu'gvlt2 on the lever k2, causing the lrod m to press down on the top of the check-valveand close it;

The reference-letters E E' represent a waterjacket through which Water passesaround the .K

vupper portion of the water-chamber @the purpose of Which is torapidl y condense the steam admitted by the valve E4.V Inlet'and outlet pipes F and G, respectively, are pro-v vided for the entrance of the water intoand from the jacket in pipe o2. H4 is an ordinary check-valve in pipe 02. The water-chambfer b is screwed and leaded to the bed-platen and cap J. A

The operation of my deviceV is as follows: l'

Steam is admitted to thechamber b through angle globe-valve E4, the chamber b having previously been filled to theV required height with water fromany suitable source.

outinto pipes g and up against pistonH. The relief-pipe 02 isY of course open, and a small percentage of the steam may at first' escape is forced-upward by thev pressure of Water thereagainst the dog 7c' on the piston-rod p' is brought into contact with the lug 71:2,l"'o``V cated on the swinging bar k2. This contact operates to swing the bar k3 on Vits pivot L and force the rod m, carrying valve-n2, downA upon the relief-pipe 02. It willbe s'e'en that a very slight, descentof, the valven2 Will'sut-A .Y

tice to close the apertures 03. Furthermore, the adjustable weight L5 is located to balance the lever k2, so that the moment lthe 'dog 7;

raises the lever k2 above the pivot L' the weight L5 assists in closingA valve n2 and reiV taining it in closed position.` Also, the ,adA-Y justment of rod im may be so regulated that the valve will be closed almostjimmediately, if need be. f The rod L2 by means ofthe adjusting-nut L4 operates to retain the -lu g Win An overflow-pipe o projects upwardy from the'A bottom of they `The steam'acting upon the water forces the latter ICO IIG

into the chamber C. However, asthe piston a predetermined position to contact with dog 7c'. The piston may continue to ascend to the full limit of its stroke, the lug c2 describing the are of a circle about L as a center and being long enough to always remain in contact with the dog 7c' until on the instroke or downstroke the nntL4 prevents the swinging bar 7a3 from descending farther. Of course as the piston rises it actuates the walkingbeam, forcing rods s downward until t-he lugs Qc 0;' engage the bed a of the device. The split sleeve t', carrying lugs fr' rc', is adjusted on the rod s so that the lugs will contact with bed-plate a at the completion of the downward stroke of the walking-beam. The rod S of course forces the swinging lever w down on the arc of a circle on `y as a center, and the pawls ct' drop back on the teeth of ratchets a2 to obtain a new hold. Simultaneously with the movement of the walkingbeam the lever d, located between the adjusting-arms and screws b3 b3 and c/ c', respectively, is oscillated until it comes in contact with one of the set-screws c, whereupon a longitudinal movement is communicated to rod e8, drawing the lower arm of bell-crank lever c* outward and forcing the flat reciprocating rod E2, which is connected to the other arm of bell-crank lever c, downward in its bearings c7 E3. It will be remembered that the levers Il and] are provided with square pins 7b2, adapted to come in contact and be locked with catch-springs h3. The drawing Fig. l shows the pin h2 on lever H' in contact with the catch-spring. New as the flat bar E2 descends the upper one of the adjustable pins f3 is brought into contact with the upper catch-hook g. This hook is forced down against the upper catch-spring h3 and presses the said springcatch backward to release the pin 7b2 on lever H'. At the same time the pin h2 on leverj' is engaging and be coming locked by the lower catch-spring 71,3. This last is caused by the central pin f3, which is in contact with lever lj' and forces it down, the pin h2 sliding on the inclined surface of lower catch-spring h3 and finally becoming locked therewith. As soon as the pin h2 on lever H is released from contact with the upper catch spring h3 the tension of springr g3 is permitted to exert itself on lever II to rock it downward on its pivot H2. This action closes the angle globe-valve El through rod J2, which is pivoted to lever H2. As soon as the steam is cut otf, a reversal of the above operations, the water in water-jacket E operates to cool the steam and condense the moisture thereof. This creates a vacuum in chamber Z), and the water column in pipes g and piston-cylinder A, which has commenced to return, having been forced above its level by the steam, is quickly returned to chamber b and piston II descends by reason of the atmospheric pressure thereon. Any air caught beneath the piston is allowed to escape through air-vent g. In order that there may be no ai r-cushion when the piston descends,

the walking-beam is actuated to raise rod .s until the lower studs a" contact with the lower side of the bed-plate a. This movement of the rod s raises the swinging lever YV, and the pawls engaging the ratchet-teeth revolve the shaft y. At the same time lever d has come in contact with the opposite one of said adjusting-screws c' the rodcS is operated to give the bell-crank lever an inward and upward movement which carries with it the flat bar E2. Then this flat bar moves upward, the lower catch-hook g is brought against lower catch-spring h3 by means of lower pin f3 to compress the spring and release pin 7b2 on leverj, the tension of spring g3 is released and tends to draw up lever j', and as the flat bar is moving upward tension is brought to bear on lever H by spring f2, thereby raising the lever, which in turn raises rod J2 and opens the angle globe-valve E4. As the piston II descends or makes its instroke, the water meanwhile reilling chamber b, any excess of Water will be forced out through pipe o2 and, raising valve n2 until the apertures o:E are above the level of pipe o2, will discharge therethrough into the chamber C, which is provided with an overflow-pipe to permit the water to escape. It will be understood, therefore, that the dog 71; by supporting lug k2 tends to retain the valve n2 in closed position against the pressure of the steam on the upstroke and onlyadmits of the valve being opened by the pressure of the water in chamber b when the dog 7a', owing to the descent of the piston, has reached a point parallel with pivot L of lever K3 and allows the water to commence to raise the valve n2. The opening of the valve and the length of the stroke thereof are regulated both by set-screw L4 on rod L2 and also by lock-nuts fm2 on rod fm'.
